Gastric bypass is the most commonly performed type of bariatric surgery in the United States. It involves creating a small stomach pouch and attaching it to the middle of the small intestine, bypassing part of the intestine. Like other metabolic surgeries, it changes the amount of food your body can digest, and changes the signals that travel between your digestive system and your brain.
The sleeve gastrectomy is a weight loss procedure that removes part of the stomach and restricts the amount of food that can be eaten. Like other metabolic surgeries, it also promotes weight loss by changing hormonal signals between the stomach, brain, and liver.
Biliopancreatic Diversion with Duodenal Switch
The biliopancreatic diversion with duodenal switch surgery, also known as the BPD/DS, is similar to gastric bypass because it involves creating a small stomach pouch and rerouting the intestines. However, the way the intestines are rerouted is slightly different. Like other metabolic surgeries, it changes the amount of food your body can digest, and changes the signals that travel between your digestive system and your brain.
One Anastomosis Gastric Bypass
Compared to the traditional gastric bypass, the one anastomosis gastric bypass (OAGB) is typically a shorter and simpler procedure. OAGB involves the creation of a small stomach pouch, roughly the size of a banana, which is then connected to a section of the small intestine, bypassing the rest of the small intestine. Like other metabolic surgeries, it changes the amount of food your body can digest, and changes the signals that travel between your digestive system and your brain.
Single Anastomosis Duodenal Switch
Single anastomosis duodenal switch (SADI), or looped DS, begins with a sleeve gastrectomy which restricts the amount of food that can be eaten. The banana-sized “sleeve” is then connected to a looped section of the small intestine. Like other metabolic surgeries, it also promotes weight loss by changing hormonal signals between the stomach, brain, and liver.

There are risks with any surgery, such as adverse reactions to medications, problems with anesthesia, problems breathing, bleeding, blood clots, inadvertent injury to nearby organs and blood vessels, even death. Bariatric surgery has its own risks, including failure to lose weight, nutritional or vitamin deficiencies, and weight regain. Patients should consult their physicians to determine if this procedure is appropriate for their condition.
